SOUTH BURLINGTON — The South Burlington School Board and the teachers’ union are hoping a fact-finding report can help them reach an agreement on a new contract.

Negotiations have been under way since November and a mediator from Boston met with both parties May 15 but was unable to resolve an impasse in negotiations.

The fact-finding report that is due mid-summer will disclose publicly the most recent offers each side has made.

But the Burlington Free Press reported neither side is willing to discuss the details of the negotiations.

“Nothing is agreed until it’s all agreed,” said School Board Chairman Richard Cassidy.

Chief teacher negotiator, Eric Stone, said the union wants a deal.

“Nothing would please us more than getting that fair, settled contract,” said Stone, a South Burlington High School math and science teacher.

The current contract expires June 30 but it includes a clause extending the terms of the contract if no new agreement has been reached.

In 2011, the board and union fought bitterly before agreeing to the current contract. The board imposed terms after the union refused to accept a proposal that would have eliminated automatic pay increases — standard in most teacher contracts — based on each year of service and additional education.

The starting salary for South Burlington teachers is just over $41,000 with a maximum salary of $85,382.
